In a feeding radiation electrode (3) of a surface mount antenna (1), a meander pattern (4) is formed locally in a maximum resonance current part (Z(Z2)) in a high-order mode (second-order mode) so as to locally form a series inductance component therein thereby making the maximum resonance current part (Z(Z2)) have a greater electrical length per unit physical length than the other parts. This makes it possible to control the difference between the resonance frequency in a fundamental mode and the resonance frequency in the high-order mode over a large range.
